Radiation Therapy News and Research

RSS

Radiation therapy (also called radiotherapy, x-ray therapy, or irradiation) is the use of a certain type of energy (called ionizing radiation) to kill cancer cells and shrink tumors. Radiation therapy injures or destroys cells in the area being treated (the “target tissue”) by damaging their genetic material, making it impossible for these cells to continue to grow and divide. Although radiation damages both cancer cells and normal cells, most normal cells can recover from the effects of radiation and function properly. The goal of radiation therapy is to damage as many cancer cells as possible, while limiting harm to nearby healthy tissue.

Radiation seed implant decreases risk of death over watchful waiting/active surveillance for prostate cancer

Prostate cancer patients cut their risk of dying of the disease in half when they receive radiation seed implants (brachytherapy) to treat their cancer, compared to those who don't receive active treatment (watchful waiting/active surveillance), within six months from being diagnosed with localized prostate cancer, according to a study presented October 31, 2007, at the American Society for Therapeutic Radiology and Oncology's 49th Annual Meeting in Los Angeles.
